SIP Trunk Service – What is it and What to Choose for Your Company? 

Managing a phone system with multiple consultants is quite a challenge. Whether you are responsible for the operation of a sales department, a call center or conducting telephone surveys, it is worth looking for an efficient technology to support daily tasks. This is where SIP Trunk comes into play, a modern alternative to traditional digital telephony. From this article, you will learn exactly what SIP Trunk is, how it works and what it can offer your company. 

What is the SIP Trunk Service? 

In short, SIP Trunk is a service that provides a modern and most importantly, efficient alternative to analog and digital telephony over ISDN PRA/BRA lines. This solution is a good choice when a company uses VoIP telephony or digital ISDN lines and the existing solutions are no longer sufficient. This is where SIP Trunk comes in, expanding the functionality of the VoIP network offered by the operator. This service allows for simultaneous handling of multiple voice and video calls via a virtual channel, known as a Trunk. During calls, the SIP (Session Initiation Protocol) is used. This technology is intended for enterprises that use a PBX system or their own telecommunication center, enabling them to connect their phone system to the operator’s network. 

How Does It Work? 

The service works by transmitting voice over the internet through multiple channels. For the solution to be effective and secure, the minimum internet bandwidth for both uploading and downloading for each individual call should be 100 kbit/s. During a call, the voice is transmitted over the IP protocol in real-time. With the SIP Trunk service, you can scale it freely, which is useful for extensive sales and customer service departments. You can also port your existing landline and mobile numbers to SIP Trunk. 

Key Benefits of SIP Trunking for Your Company 

Using the SIP Trunk service is becoming increasingly popular among savvy entrepreneurs who have telephone customer service or sales departments. Nowadays, it is hard to imagine scaling a business and building its market position without direct communication with clients, potential clients, business partners and other stakeholders. SIP Trunk would not be so popular if it did not offer certain benefits. Below are some of them. 

Optimization of Telephone Call Costs 

Undoubtedly, one of the business benefits is the optimization of telephone call costs. It is estimated that skillful implementation of SIP Trunk in a company can generate savings of up to 60%. This is because, as the needs grow, additional channel packages (Trunks) can be purchased from the provider to handle a larger number of calls at once. At the same time, there is no need to buy additional equipment or modify or configure the previously prepared interface. In this respect, using SIP Trunk is not only efficient but also intuitive. The scope of the service can be increased or decreased at any time, providing a flexible solution that supports business scalability. 

Better Reach to Customers 

SIP Trunk also improves customer reach. This is because the caller can choose any company number assigned to the service, whether it is a landline, mobile or a completely new 80x hotline number. If customers do not answer, changing the number can help. With the SIP Trunk service, you can use any numbering zone. You can use numbers from a preferred region, making it easier to reach the customer. From experience, we know that customers are more likely to answer calls from numbers in their vicinity. This type of contact generates greater trust from the start, as the caller’s location is assumed to be close to the recipient’s. 

Additional Functionalities of the Phone System 

Among the key business benefits, it is worth noting that SIP Trunk increases the functionality of the existing phone system. This makes customer service even more efficient, translating into improved financial results for the company. Examples of functions offered by SIP Trunk include: 

Use these features to better serve your customers. Call recording is useful, for example, during the onboarding of new employees and in efforts to raise service standards. In extreme cases, it can be helpful in resolving conflicts between the company and the customer.
